This invention relates to-spinning structures, and especially to a spin toy' or the typeemploying the jet principle foreifecting the rotational movement of the spinnablemember. 1

An-object of this invention-is to produce a and improved assembly of parts that employs the jet principle forv the: generation of such forces as'will impart rotational movement, to a-shaft mounted blade of a spin toy.- I

Another object of this invention is to produce a spinning toy having the features of enabling the admission of fluids intoa rotatable. blade in a manner which does not effect rotational movement thereof, but on emission from offset-parts of the blade, such tangentialforces are generated as will cause the-rotatable member to spin.;

A further object is to producegastructure of the type described consisting of relatively few simple parts readily manufactured and'assembled on a mass production basis of; low cost materials into a product adapted to operate in re: sponse to the movement offluids received froma fluid source and released through properly positionedjet ports. i

These and other objects and advantages of this invention will hereinafter appear, and-for pur: poses of illustration, but not of limitation, em bodiments of the invention are shown-inthe accompanying drawings in which,

the exhaust ports in thediagonallydisposed-con Inone aspect of the invention, an article, of manufacture produced consisting .of a hollow blade,. which centrally journalled onv a shaft through which a fluidis introduced-to the blade. Since the incoming fluid generates forces operating axially of the blade'center, its admission in no way affects or retards; the rotationalmovement of the blade inane-direction or the other. However, on emission of the fluid from the blade through ports providedin ,edge portions of the blade, which are ofl'set from; the center, such I szi e new 's-claims. (on. 46-41) tangential forces are generated as will urge the movement of the blade in a direction to effect rotational movement thereof about the shaft. Thus, the blade may be spun on the end of. the shaft merely by admission thereto of fluids supplied from-a fluid source, the rotational movement relating proportionally to the rate of fluid emission.

. Referring now to the drawings, 10 indicates a blade consisting. affront andrear walls H and l2.respectively, joined at their adjacent edges to provide a fluid tight hollow structure. Although the hollow blade may-be contoured to simulate any desirable elongate member, such for example as an airplane propeller or an ellipsoidal member, for simplicity and ease of manufacture, it is preferably formed rectilinear as is readily obtained, by partially crushing .tubular stock and then sealing the open ends, by folding and sealing the adjacentedge portions of rectangular sheet stock, or by such fabrication processes as molding, stamping, casting and the like of rigid and formable materials such as paper, plastics, metal, wood and the like.

,The blade I0 is centrally journaled on a hub structure through which the driving fluid is admitted, as previously pointed out. Full understanding of the hub structure may be had with reference to its method of manufacture. Sufiice it: to. say that a central'aperture l3 is'provided in the rear wall 12, which aperture is adapted to be:substantially concealed by a separate disc member I l-having a central aperture 15 that is lined with a grommet l6. Before the disc member I4 is fixed to the rear wall 12, a tubular coupling I! having a flared end portion l8, the maximum diameter of which is greater than that of the grommet, is inserted through the grommet in a manner to dispose the flared end portion within the .blade when assembled. In the mounted position, the disc member is-sealed to the blade so that they rotate together about the tubular coupling, which withthe grommet providesbearing metal surfaces that enhances their relative rotational movement.

Telescoping withthe outwardly extending end portion of the tubular coupling 11 is an extension in the form of a blow pipe. l9 for connecting the coupling with a fluid source. When air comprises the fluid means for actuating the blade, it may be supplied by blowing from the mouth through a rigid blow pipe, a pressure pump, or an air accumulator.

28 and 2| indicate outlet ports formed in respective diagonally, disposed corner portions of the blade I I], which ports are adapted principally to face laterally, so that, on emission of the fluids therefrom, complementary tangential forces are generated which effect balanced rotational movement of the blade. It is apparent that eq-ually suitable driving forces may be generated if the port apertures are formed solelyto be disposed in the lateral edge portions of the blade, it being only necessary in such instances that the apertures beipositioned' to one side of the transverse blade center in one edge22 and to the other side of the center in the other edge 23. Thus, the generated tangential forces will be additive and not counteracting, to impart balanced operation of the blade.

For purposes of rigidity and design, another disc member 24 is fixed to the outer wall! I and, the over extending portion of the disc member [4 with which it coincides, and the surfaces "of the blade member and discs may be tinted in a man-. ner to produce novel and attractive designs and effects while spinning.

Operation, en l i u he ai s qree into the hollow blade, as by blowing through the blow pipe, such forces are created in the hollow blade s will u e he bl de. o tw rdly-axia l o t e b wp p hi ncremen being e t i d upon engagement of the'fiared end portion l of the coupling l1 and thegrcmmet l 6.

ports, which fluids on emission generate such tane tiel orc s s o ur e he mo ment h blade in the direction opposedto the fluid flow, thereby to effect rotational movement of the blade. The spinning movement of the blade continues a short time evenafter the ad,- mission of fluids has ceased view of the forces of inertia hi ave be e erated. Whena.

liquid is used as the driving fiuid, a spray is en iit ted from the ports Which in combination with the spinning blade adds to the novel and attractive effects.

A modified form of the invention is illustrated,

in Figures 4 and 5 ofthe drawin s. inwhich the blade structure is substantially the same as that described with reference to Figures 1 to 3 inclue sive, the differences residing principally in the structure and assemblyof the central hub portion.

The illustrated embodiment comprises a blade 30 having outer and inner walls 3| and 32 respectively, the outer wall 3! having a central aperture 33 which is larger in diameter than anarcially aligned aperture 34 formed in the inner wall 32. The unmodified end portionof a tubular blow. pipe 35, which is flared at the other end 36,.is in-.

serted first through the larger aperture and then,

the smaller until the flared end portion 36. passes through the first but is engaged and stopped by the peripheral edge portion of the latter. Thereafter the opening 33 is sealed bya cover member, 31 which is fixed to the outer wall 3| of the blade.

It is apparent that the latter describedmodification is simpler and involves fewer steps. and parts in its assembly and manufacture. However, in an assembly of the type described, it is desirable that such materials be used as will with: stand the forces tending to effect disengagement of the blow pipe from the apertured blade, and

also will enable the free rotational movement of v the one relative to the other. For such purposes the latter structure preferably isformed of such.

4 rigid but formable material as treated paper, plastics, sheet metal and the like.

A further simplification differing only in the method of manufacture and assembly of the spin toy, is illustrated in Figure 6. In this form, the tubular member 40 is illustrated as being formed of a rectangular sheet of paper or the like subdivided lengthwise into three substantially equal sections 4|, 42 and 43, one outer section 4! having a cen- 'tral aperture 44 for receiving theflared end portion 45 of the tubular member "46. The other outer section 43 is provided with a laterally extending slot 41, the inner end portion of which tions are folded upon each other as illustrated.

" In this manner, the spinning device may be formed of but twoparts', the rectangular sheet 40 andthe tubular member 46 which in assembly is first-inserted through the aperture 44, then the center section 42 is folded over so as to cover the flared end portion, 4 5, the outer section 43 isthen foldedpver. the section 4I so.that the tubular. member 46,,passesthrough the slot 41. The ra-.- dial ends of the blade are thensealedwith .adhe: i Q Or sea in st i s whiletheedgeof theouter sec ion. 3 .is. IaStenei-to theadj acent section :by. dhe ves, staplin 0.1. other... sealing. strips. 48. ince t epressures generated by. the. incoming.

vfluids suffice to force. ,the isection 4|. tightly to bear again t.theahuttingsection. 43, it .is apparent. that onlymeans tacking; the one section. 43- to thesectionfil wflL-suffice; In this manner, a double ply of. sheetjmaterialalies adjacent the fiangediend portionbf. the tubular .member, enabling the use thereof .withoutlreinforoing strips.

In a similar manner, it isreadily seen that the toy may also be formed with a centralape'rture only in the central section 42,. the outer section's being then folded one oil-the other over the flared end portion 4501 the tubular-member after which the radial .ends aresealed and the lateral edges connected as previously described.

Manifestly, I have produced a new and improved spinning toy which may be formed of readily available and formable materials into relatively few parts that are easily assembled to produce a rotatably'mounted blade member that.

ports may be effected without departing .from the spirit'of'the invention, especially as'd'efined in the appended claims.
